/GH (Enable _pexit hook function)

Calls the _pexit function at the end of every method or function.

Syntax

/GH

Remarks

The _pexit function isn't part of any library. It's up to you to provide a definition for _pexit.

Unless you plan to explicitly call _pexit, you don't need to provide a prototype. The function must push the content of all registers on entry and pop the unchanged content on exit. It must appear as if it had the following prototype:

void __declspec(naked) __cdecl _pexit( void );

This declaration isn't available for 64-bit projects.

_pexit is similar to _penter; see /Gh (Enable _penter Hook Function) for an example of how to write a _penter function.

To set this compiler option in the Visual Studio development environment

  2. Select the Configuration Properties > C/C++ > Command Line property page.

  3. Enter the compiler option in the Additional Options box.
